OpenSlide returns uncompressed ARGB; the demo scripts handle the 
compression.  In fact, both of them were hardcoding the compression 
level.  I've added a -Q/--quality command-line option; you can pull the 
updated scripts from Git.

Note that this only matters for JPEG, since PNG is lossless.  (There is 
an optimize mode for PNG which can produce slightly smaller images, but 
it is disabled for the reasons given in [1].)

That would be great!  The best place for the document is probably the 
wiki[2].
